The Lowdown
Alright, Rusty here, let’s chew through what’s ahead for Jaconé over the next couple of weeks.
First off, it’s a slow starter, but there’s some real fire in the second half. Water temp is about 72°, right on the money for this time of year.
The first decent window is Wednesday afternoon, July 29th. It’s small – only 3 ft of south swell – but with a light east wind at 3 mph, cross-off, and a moderate combined energy of 201, it’ll be clean and fun for a lazy session.
Thursday, July 30th is pretty much a no-go. Onshore wind in the morning and a choppy 3 ft cross-on swell in the afternoon.
Friday, July 31st has a clean morning with 3 ft of south swell and a cross-off east breeze at 9 mph, but it’s nothing special. The afternoon drops to 2 ft with a 14-second period – that’s a long groundswell but too small and inconsistent for much.
Saturday morning, August 1st is a real bright spot. 3 ft of south swell at 12 seconds, combined energy of 288, and clean offshore northeast wind at 9 mph. Smooth, lined up, and worth getting out of bed for. The afternoon gets blown out.
Sunday and Monday are small – 2 ft to 3 ft, with clean mornings but short, weak period. The swell swings east at 6 seconds, which is windswell. Not much power behind it.
Now Tuesday morning, August 4th fires up. Swell hits 5 ft from the east-northeast, period 7 seconds, combined energy 528 (strong). It’s clean with light offshore wind. That’s a proper pulse. The Tuesday afternoon also has strong energy at 540, but the swell drops to 3 ft from the south at 13 seconds – longer gaps between sets, better shape.
Wednesday morning, August 5th is glassy. North-northeast wind at just 3 mph, 3 ft south swell at 11 seconds, combined energy 324. That is clean, smooth, and inviting. The afternoon turns onshore.
The next huge window is Tuesday, August 12th. The morning shows 3 ft of south swell at a very long 16 seconds, combined energy 545. Light cross-off east-southeast wind. Clean, but the long period might make it run a bit straight at the beach.
But the champion session of the whole outlook is Tuesday afternoon, August 12th. 6 ft of south swell at 15 seconds, combined energy hits a massive 1520 – that is powerful, heavy water. Wind is light cross-off at 6 mph. Clean, strong, and excellent for experienced surfers. Anything over 8 ft is expert-only, but at 6 ft this is still a serious push.
Wednesday morning, August 13th is also firing – 6 ft of south swell at 14 seconds, combined energy 1781, with gentle offshore east-northeast wind. That’s stacked energy and clean conditions. The afternoon gets a bit rough, but the morning will be all-time.
So, first week is mellow with a couple of good clean windows, but the second week – August 4th, the morning of the 5th, and especially August 12th afternoon and 13th morning – those are the ones to aim for. Being more than a week out, it’s a promising look, not a guarantee, but man, the potential is there.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
